1. If your product is deployed on WebSphere Application Server (WAS) and your
deployment does not use an Eclipse based client nor the RM Browser plugin,
then it is sufficient to continue using the existing version of your IBM
Rational product, and only upgrade the JRE in the WAS server.
2. For the below remediations, if you have a WAS deployment, then WAS must
also be remediated, in addition to performing your product upgrades. Follow
instructions at Security Bulletin: Multiple Vulnerabilities in IBM(R) Java
SDK affect WebSphere Application Server April 2019 CPU to get the WAS
3. If you are deploying the Rational products to a WAS Liberty or a Tomcat
Server, you will need to follow the instructions below to upgrade the JRE,
and then must also configure to complete the upgrade process:
o Stop the server: Navigate to the Server directory in your Ratonal product
installation path and run this script: server.shutdown
o Navigate to the server directory in your Rational product installation
path, open server.startup script using prefered text editor (e.g., Notepad
for Windows or Vim Editor for Linux) and add one more option to the
healthcenter parameter set:
- Search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in
server.startup script to find the line containing the health center
NOTE: For some Rational Collaborative Lifecycle Management versions,
-Dcom.ibm.java.diagnostics.healthcenter.agent parameter may not be
found in the server.startup, in this case the update is not needed and
you can start using your server.
Comment out the line (where HEALTHCENTER_OPTS parameter located) by
inserting "rem " at the beginning of the line:
set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
rem set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
Comment out the line (where HEALTHCENTER_OPTS parameter located) by
inserting "# " at the beginning of the line:
export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
# export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
o Start the server. Navigate to the Server directory in your Rational product
installation path and run this script: server.startup.
STEPS TO APPLY THE REMEDIATION:
1. Optionally, upgrade your products to an Extended Maintenance Release
version: 6.0.2, 6.0.6 or 22.214.171.124.
2. Optionally, apply the latest ifix for your installed version.
3. Obtain the latest Java JRE CPU update for the IBM Java SDK using the
